In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at compile time. We thus need to add HAS_IOPORT as dependency for those drivers requiring them. For the DEFXX driver the use of I/O ports is optional and we only need to fence specific code paths. It also turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need the !S390 dependency and successfully builds the bpqether driver.

If you want to connect your Linux box to an amateur radio, answer Y
|
|
here. You want to read <https://www.tapr.org/>
|
|
and more specifically about AX.25 on Linux
|
|
<https://linux-ax25.in-berlin.de>.
|
|
|
|
Note that the answer to this question won't directly affect the
|
|
kernel: saying N will just cause the configurator to skip all
|
|
the questions about amateur radio.

This is the protocol used for computer communication over amateur
|
|
radio. It is either used by itself for point-to-point links, or to
|
|
carry other protocols such as tcp/ip. To use it, you need a device
|
|
that connects your Linux box to your amateur radio. You can either
|
|
use a low speed TNC (a Terminal Node Controller acts as a kind of
|
|
modem connecting your computer's serial port to your radio's
|
|
microphone input and speaker output) supporting the KISS protocol or
|
|
one of the various SCC cards that are supported by the generic Z8530
|
|
or the DMA SCC driver. Another option are the Baycom modem serial
|
|
and parallel port hacks or the sound card modem (supported by their
|
|
own drivers). If you say Y here, you also have to say Y to one of
|
|
those drivers.

Information about where to get supporting software for Linux amateur
|
|
radio as well as information about how to configure an AX.25 port is
|
|
contained in the AX25-HOWTO, available from
|
|
<https://www.tldp.org/docs.html#howto>. You might also want to
|
|
check out the file <file:Documentation/networking/ax25.rst> in the
|
|
kernel source. More information about digital amateur radio in
|
|
general is on the WWW at

DAMA is a mechanism to prevent collisions when doing AX.25
|
|
networking. A DAMA server (called "master") accepts incoming traffic
|
|
from clients (called "slaves") and redistributes it to other slaves.
|
|
If you say Y here, your Linux box will act as a DAMA slave; this is
|
|
transparent in that you don't have to do any special DAMA
|
|
configuration. Linux cannot yet act as a DAMA server. This option
|
|
only compiles DAMA slave support into the kernel. It still needs to
|
|
be enabled at runtime. For more about DAMA see
|
|
<https://linux-ax25.in-berlin.de>. If unsure, say Y.
